Abstract
Use of Keplerate type polyoxomolybdates of the general structure Mo72M30, wherein M is selected from the group consisting of Fe, Cr, V or Mo2, for decontaminating aqueous media (water) from inorganic and organic pollutants.
Claims11
A method comprising decontaminating aqueous media from inorganic and organic pollutants with a Keplerate type polyoxomolybdate of the general structure Mo72M30, wherein M is selected from the group consisting of Fe, Cr, V or Mo2, in combination with electromagnetic radiation having a wavelength exceeding 400 nm wherein the Keplerate type polyoxomolybdate is used in combination with a persulfate as an oxidizing agent.
A process for the decontamination of aqueous environments, the process comprising:
- adding a Keplerate type polyoxomolybdate of the general structure Mo72M30, wherein M is selected from the group consisting of Fe, Cr, V or Mo2, and a persulfate as an oxidizing agent to the aqueous environment forming an aqueous solution/slurry, and
- thereafter, irradiating the aqueous solution/slurry with electromagnetic radiation having a wavelength exceeding 400 nm.
A process for the decontamination of aqueous environments, the process comprising:
- flowing an aqueous solution comprising a persulfate as an oxidizing agent over a selected carrier while irradiating the aqueous solution with electromagnetic radiation having a wavelength exceeding 400 nm,
- wherein the selected carrier comprises a Keplerate type polyoxomolybdate of the general structure Mo72M30, wherein M is selected from the group consisting of Fe, Cr, V or Mo2, supported on a solid support.
